THERAPY SHOE
Technical Field
The present disclosure generally relates to systems and methods for providing
medical therapy and specifically to systems and methods for assisting the
stimulation of
blood flow, reducing edema, reducing leg cramping, treating plantar fasciitis
in the foot,
and/or promoting recovery from athletic excursion. More specifically, the
present disclosure
generally relates to a shoe configured to hold a removable and/or integrated
device that
applies pressure to a wearer's foot to treat various ailments and/or provide
athletic recovery
after physical exercise.
Background
In order to enhance circulation in a person's body, particularly in the feet
and legs,
periodic or cyclic compression of tissue, such as plexus regions of the foot,
at predetermined
timed intervals is beneficial. Under normal circumstances, blood moves up the
legs due to
muscle contraction and general movement of the feet or legs, such as when
walking. If a
person is immobilized, unable to move regularly, or has poor circulation
brought on by
disease, the natural blood return mechanism is impaired, and circulatory
problems such as
ulcers and deep vein thrombosis can occur.
To mitigate these problems, it is desirable to concentrate a compression force
against
veins throughout the legs and/or feet. Current systems are primarily based on
pneumatic
compression devices that squeeze the entire foot, calf, or thigh. These
systems require
significant power, and are inefficient because they provide high levels of
force across the
entire foot or leg rather than focusing in on those areas with the highest
concentration of
blood vessels. In addition, these systems may include air bags that can
rupture at the seam,
especially with high pressure within the bag.
In various current devices, tethered air lines limit mobility, and can lead to
injury
should the person attempt to walk while the device is in use. Further,
existing devices may
not be suited for continuous usage. Users cannot walk with them, or move away
from the
compression unit. The device must be removed before a user can walk.
Additionally,
current devices lack the ability to track and report user usage and
compliance. Also, most
pneumatic devices are quite noisy and can cause irritation of the skin leading
to ulcers.
Furthermore, current devices do not blend in well with ordinary clothing and
stand
out as medical devices. It would be advantageous to provide a therapy shoe
that could be
worn as ordinary clothing and not be an obvious medical aid.

160, 163, 165, configured to receive and retain a portion of a foot, such as
dorsal surface, the
heel, and/or the like, as is known. Moreover, therapy shoe 100 may comprise
any suitable
number of straps. In one exemplary embodiment, each strap 160, 163, 165
comprises a first
side and a second side. The first side and/or second side are configured to
comprise a
portion of a fastener, such as a first hook and loop fastener portion and/or a
second hook and
loop fastener portion configured to mate with and couple to an opposite hook
and loop
fastener portion, on at least one of a top surface and/or or bottom surface of
the first side
and/or second side.
In an exemplary embodiment, with regard to strap 160, 163, 165, the first side
is
configured to have an opening which a portion of the second side may be fed
through. A
portion of second side of strap 160, 163, 165 is fed though an opening in a
first side of strap
160, 163, 165 and is adjustably anchored using a fastener, such as a hook and

of strap 160, 163, 165, to provide comfort for a user. Moreover, straps (e.g.
strap 160, 163,
165) may be configured to accept variances in individual feet (e.g., height of
arch, curvature
of arch, width, length, and/or the like).
In other exemplary embodiments, straps (e.g. strap 160, 163, 165) are
eliminated and
other known footwear constructions are provided. These examples include, but
are not
limited to, laces, buttons, tongues, designer straps (such as those on a high
heel shoe), and
other similar constructions. Moreover, any material now known or used in the
future to
construct footwear may suitably be used, and is considered to fall within the
scope of the
present disclosure.
In an exemplary embodiment, a covering, such as a waterproof covering, may be
coupled to therapy shoe 100. For example, a bag or shroud may be coupled
around therapy
9

WO 2011/109725 PCT/US2011/027220
shoe 100 to prevent unwanted elements such as sand, water, dirt, debris,
and/or particulate
from coming into contact with therapy shoe 100. In various exemplary
embodiments,
therapy shoe 100 may at least partially comprise natural rubber, synthetic
rubber, polymer
composites, or other waterproof and/or water-resistant materials.
In various exemplary embodiments, therapy shoe 100 is coupled to an external
object. For instance, the external object may be a fixed surface, such as a
wedge in a fixed
position coupled to the ground. The external object may be an elevated
surface, such as a
footrest. Alternatively, the external object may be coupled to and/or comprise
a movable
object such as a portion of a bed, chair, hospital bed, cart, or wheelchair.
The coupling may
be by any suitable means, such as magnetic, mechanical, hook and loop
fastener, strapping,
fastening, lacing, tying, and/or the like.
In accordance with an exemplary embodiment, therapy shoe 100 is configured to
be
fabricated integral to a shoe, boot, sandal, or other footwear. Moreover,
therapy shoe 100
may be configured with various sizes, including industry standard sizes. For
instance,
therapy shoe 100 may be formed in a size compatible to and related to a foot
size such as at
least one of. USA men's sizes: 6 through 16 (in any suitable width such as C,
D, E, and/or
the like); USA women's sizes: 4 through 14 (in any suitable width such as
narrow, average,
wide, extra wide, and/or the like); USA children's sizes: 6 through 13 and I
through 3;
European men's sizes 35 through 51; Europeans women's sizes 35 through 48.5;
universal:
small, medium, large, XL, XXL, and/or the like. Although specific shoe sizes
have been
recited herein, any size item of footwear is considered to falls within the
scope of the present
disclosure.
Moreover, in accordance with an exemplary embodiment, therapy shoe 100 is
configured to be one-size-fits-all. For instance, portions of therapy shoe
100, such as
coupling portion 102 and/or housing 101, may be expandable and/or retractable
to
accommodate a variety of foot sizes, widths, and lengths. In various exemplary
embodiments, therapy shoe 100 is configured to be one of shaped to receive a
right foot,
shaped to receive a left foot, or shaped to receive a right or left foot. In
certain exemplary
embodiments, therapy shoe 100 may be provided in pairs, for example two
therapy shoes
100, one each for the right foot and the left foot.
With reference now to FIG. 4, in accordance with an exemplary embodiment, a
user
(and/or caregiver, third person, etc.) may insert therapy device 400 into a
cavity of therapy
shoe 100 (not shown). Straps 160, 163, 165 (from a first closed position) of
therapy shoe

CA 02792111 2012-09-04
WO 2011/109725 PCT/US2011/027220
100 are opened. A portion of a user, such as a lower extremity (e.g. foot), is
inserted
between a first and second side of straps 160, 163, 165, and comes into
contact with surface
120. The location of the portion of a user with respect to surface 120 and/or
other
components of therapy shoe 120 may be a function of the location of therapy
shoe 100's
elements and/or a user's individualized anatomy. Once a portion of a user is
in a desired
position, straps 160, 163, 165 may be adjusted and/or closed (e.g., from a
second position to
a first closed position). Therapy device 400 may be activated through opening
110.
In various exemplary embodiments, therapy shoe 100 is configured to withstand
force provided by a user while therapy shoe 100 is coupled to the user. For
instance, a user
may provide a force to therapy shoe 100 by standing or walking while coupled
to therapy
shoe 100. A user may move at any pace while coupled to therapy shoe 100. It
will be
appreciated that, in certain embodiments, therapy shoe 100 is configured to
allow a user to
remain mobile; however, in other exemplary embodiments, therapy shoe 100 is
configured
for use by a user who remains non-ambulatory while coupled to therapy shoe
100.
For example, in certain exemplary embodiments therapy shoe 100 is configured
as a
"walking" shoe. In these embodiments, therapy shoe 100 may be utilized by a
wearer in a
manner similar to a conventional shoe. In these embodiments, therapy device
400 may be
configured to be inactive when the wearer is walking, for example in order to
prevent wearer
discomfort, damage to therapy device 400, and/or the like. In other exemplary
embodiments, therapy show 100 is configured as a "non-walking" shoe. In these
embodiments, therapy shoe 100 may be utilized by a wearer when non-ambulatory.
In these
embodiments, therapy device 400 may be configured to be constantly active,
active at a
scheduled interval, and/or the like.
With reference now to FIG. 6, in various exemplary embodiments therapy shoe
100
may be coupled to and/or utilized in connection with a compression garment,
for example
compression sock 680. Compression sock 680 may be configured to work in a
complementary manner with therapy device 400, for example in order to treat
and/or prevent
deep vein thrombosis, to facilitate athletic recovery, and/or the like. In an
exemplary
embodiment, compression sock 680 is releasably coupled to therapy shoe 100 via
one or
more of zippers, snaps, straps, buttons, hooks, hook and loop fasteners,
and/or the like. In
other exemplary embodiments, compression sock 680 is permanently coupled to
therapy
shoe 100, for example via gluing, stitching, and/or the like.

CA 02792111 2012-09-04
WO 2011/109725 PCT/US2011/027220
Compression sock 680 may comprise any suitable flexible material and may be
configured with any suitable dimensions, shapes, curves, stitching, and/or the
like, as
desired, in order to at least partially receive and/or compress a portion of a
limb. Moreover,
compression sock 680 may be configured with any suitable level of compression,
for
example from between about 5 mmHg to about 50 mmHg. Compression sock 680 may
be
configured as knee-high, as thigh-high, as pantyhose, and/or in any other
suitable
configuration.
Because compression sock 680, when wom by a user, compresses the surface
veins,
arteries, muscles, and other soft tissue, circulating blood is forced through
narrower
circulatory channels, increasing the arterial pressure. This distribution of
blood in the limb
of a wearer can facilitate improved results (for example, increased blood
circulation,
decreased pooling of blood in the feet and lower extremities, etc.) responsive
to operation of
therapy device 400. Stated another way, when compression sock 680 and therapy
device
400 work in tandem, blood flow is further concentrated and increased, with the
result of
facilitating athletic recovery, reducing deep vein thrombosis, reducing edema,
and/or the
like.
The present disclosure has been described above with reference to various
exemplary
embodiments. However, those skilled in the art will recognize that changes and
modifications may be made to the exemplary embodiments without departing from
the
scope of the present disclosure. For example, the various operational steps,
as well as the
components for carrying out the operational steps, may be implemented in
alternate ways
depending upon the particular application or in consideration of any number of
cost
functions associated with the operation of the system, e.g., one or more of
the steps may be
deleted, modified, or combined with other steps. Further, it should be noted
that while the
methods and systems for aiding compression described above are suitable for
use on the
foot, similar approaches may be used on the hand, calf, extremities or other
areas of the
body. These and other changes or modifications are intended to be included
within the
scope of the present disclosure.
In the foregoing specification, the disclosure has been described with
reference to
various embodiments. However, one of ordinary skill in the art appreciates
that various
modifications and changes can be made without departing from the scope of the
present
disclosure as set forth in the claims below. Accordingly, the specification is
to be regarded
in an illustrative rather than a restrictive sense, and all such modifications
are intended to be
